That sounds like you've got the basic compliment. As I recall from my days running a network of them, the base DN10K has four cards (Network, video, CPU and memory). Extra slots were available for an FPU, more memory (and maybe a disk controller?). The CPU should be easy to identify by the presence of a MC68010 chip. The DN10K's typically did not have their own disk drives; instead they booted (and paged!) off of a "partner" server node having the disk. The network adapters (in a plastic box that screwed onto the back) were spectacularly flaky on those machines.
